sql - ActiveRecord Joins -

i'm trying use activerecord best of it's ability , having trouble doing joins in way like.

here how models set up:

class model     has_many :likes end  class     belongs_to :model     belongs_to :user end  class user     has_many :likes end

i likes 'model' object , there users made like. activerecord query is

@model = model.find(params[:id]) @users = @model.likes.joins(:user)

however, last line of code returns like, not user. there way use joins appropriately , want?

thanks,

you can has_many :through:

class model     has_many :likes     has_many :users, :through => :likes end

or can eager load users , join in ruby:

@users = @model.likes.includes(:user).map(&:user)
